Bioaugmentation is the addition of archaea or bacterial cultures required to speed up the rate of degradation of a contaminant.In a place filled with contamination, microbial life usually finds it as a place to call home. The biological material that originated in this contaminated area is able to break down waste, but when the amount of waste overloads it needs help from a foreign form to increase performance in breaking down chemicals. Bioaugmentation develops the biological material in order to smoothly break down certain compounds. When a microbe is added to the contaminated area, they are able to improve the biological material’s capability to behave in a manner as to break down contamination that was already broken up before.
